A knob assembly and an appliance having a knob assembly are provided. The knob assembly may include a knob configured to be rotatably installed, a knob ring configured to surround the knob and to be rotated independently from the knob, a spring configured to provide an elastic force so as to return the knob ring toward an initial position when the knob ring is rotated to a position spaced apart from the initial position, and a magnetic force provider configured to provide a magnetic force to return the knob ring to the initial position when the knob ring is at a position adjacent to the initial position.

An operator control device has an actuation unit on a console unit. The actuation unit movable between an idle position and one or more actuation positions. The actuation unit is fixable in the idle position by a retaining device. In order to leave the idle position, it is necessary to overcome a retaining force provided by the retaining device. The retaining device has a coupling device with a coupling element that is magnetically couplable to the actuation unit and to the console unit in order to magnetically fix the actuation unit in at least the idle position.

A speed regulating hand brake mechanism and method for speed regulation of the speed regulating hand brake mechanism is disclosed. The mechanism includes: a housing, wherein an installation cavity is defined inside the housing; a speed regulating button is hinged to the side wall of the housing; an installation cavity is internally provided with the driving part hinged to the speed regulating button; the rack is hinged to the driving part and can slide along the inner wall of the installation cavity in a horizontal direction after receiving the pressing force transmitted from the speed regulating button; the encoder is fixed on a first fixing plate in the installation cavity, the rack drives a gear arranged at the top of the encoder to rotate, and changes the code value output by the encoder; the elastic end of the return piece is located inside the speed regulating button.

The invention relates to a floor mounted brake pedal for an electrically controlled vehicle brake, comprising a first pedal lever, a second pedal lever arranged in front of the first pedal lever, a pedal platform having a stepping area and a shaft protruding from the stepping area in a forward direction, a first pedal sensor for detecting a position of the brake pedal, and a second pedal sensor for independently detecting the position of the brake pedal.

An electronic device comprises a rotational operation member and a control unit that controls an angle of rotation at which to generate a clicking sensation in the rotational operation member. The control unit controls the angle of rotation based on a division of a setting to be changed in accordance with a rotational operation of the rotational operation member.

A foldable pedal apparatus of a vehicle with a hysteresis module, may include a pedal pad is in a popped-up state of protruding from a pedal housing to be exposed toward a driver, in a manual driving mode in which the driver directly drives the vehicle; the pedal pad is in a hidden state of being inserted into the pedal housing and blocked from being exposed to the driver, in the autonomous driving mode in which the driver does not directly drive the vehicle; and hysteresis may be implemented by a hysteresis module when the pedal pad is operated.

In an embodiment a magnetorheological fluid-based haptic knob apparatus includes a housing, a solenoid coil mounted inside the housing, the solenoid coil configured to generate a magnetic field thereby providing magnetic flux, a shaft connected to the housing and including a rotational rod, wherein the shaft is configured to generate a plurality of modes and a magnetorheological fluid accommodated inside the housing, the magnetorheological fluid configured to form a magnetic chain in response of the magnetic flux.

An accelerator device having an organ structure includes: a pad configured to be pressed by a driver; a case configured to be attached to a vehicle body; an inside movable mechanism housed in the case; and an arm that passes through an opening formed in an outer wall of the case and connects the pad to the inside movable mechanism. The arm has a rectangle shape in a cross section. An entire circumference of the opening is surrounded by a protrusion protruding toward the pad. The protrusion includes an upper surface, and the upper surface has an inclination portion that slopes down rightward or leftward, when viewed from the pad.

A user interface apparatus for controlling a marine vessel. The apparatus includes concentric positioned mechanical stick, block and ring for setting a control parameter, electric motors, and electric visual elements. The apparatus also includes one or more processors configured to operate the user interface apparatus in a plurality of operation modes, each operation mode with a distinct configuration, retrieve distinct settings for the tactile feedback and/or the visual feedback, and control the tactile feedback given by the one or more electric motors and/or the visual feedback given by the one or more electric visual elements based on the retrieved distinct settings during setting a selected control parameter mapped to the mechanical stick, block or ring.

A lever (3) for the temporary disengagement of a parking lock (2) of a vehicle drive unit (1). The lever (3) comprises a fixing piece (31) for fitting the lever (3) onto a parking lock shaft (26), which extends inside the vehicle drive unit (1) and serves to actuate the parking lock (2). The lever (3) is a hand lever with a gripping handle (32). The gripping handle (32) is designed to enable a user to apply a manual force for manual actuation of the lever (3). When the lever (3) is fitted on the parking lock shaft (26) and moved, the parking lock shaft (26) is moved from an engagement position to a disengagement position. In the disengagement position, by further movement of the gripping handle (32) into a locking position, the lever (3) is blocked against a reverse movement out of the disengagement position.
